1. FTTH Technology and Standards Roadmap

2. Calix Background and Perspective
David Russell, Solutions Marketing Director, Calix
Responsible for the marketing of Calix’ fiber access solutions.
2010 Chairman of the FTTH Council Board of Directors
Who is Calix?
The largest provider of broadband to rural areas
40% of US service providers rely on Calix access platforms for DSL and fiber access
60% of all U.S. FTTH service providers use Calix
Internet bandwidth demands fiber
Stage 3 of the internet: Textual  graphical  video
Video =Broadcast transitioning to internet based
Today=5 Mbps  5 yrs=100 Mbps  10 yrs=1 Gbps
Future proofed infrastructure, no reinvestment required
ONT functionality now can accommodate 1 Gbps (up/down) in to the home
Outside plant now cheaper than HFC, requires no reinvestment

3. Current FTTH Standards
U.S. Service Providers
Deploying Technology
2.5 GPON ITU standard G.984
2.5 Gbps downstream (1490nm)
1.2 Gbps upstream (1310nm)
Cable TV support (1550 nm)
Replaced BPON
1 GE P2P Ethernet IEEE 802.3ah
1 Gbps down/up (1490/1310 nm)
1 GE EPON IEEE 802.ah
1 Gbps downstream (1490nm)
1 Gbps upstream (1310nm)
Nov. 2009
Nov. 2008

4. Next Generation FTTH Standards
10G GPON (NGPON1)
987.1/987.2 completed in September 2009
10 Gbps downstream (1577 nm)
2.5 and 10 Gbps upstream (1270 nm)
Coexists with on the same fiber with 2.5 GPON
Full standard by June 2010, deployments in 2012
Beyond 10G GPON (NGPON2)
Thinking/talking /technology presentation stage
WDM PON is a candidate technology
Does not require ODN compatibility with today’s 2.5 GPON
10G EPON (XEPON) 802.3av
Ratified in September 2009
1 Gbps (1310 nm) and 10 Gbps upstream (1270 nm)
Deployments likely in 2010 and 2011

Bandwidth
10/2.5, 10/10 shared
10/1, 10/10 shared
Positives
Compatible with existing GPON
First completed
Key challenges
10 Gbps upstream not viable for single family units
10 Gbps upstream not viable for single family homes; 1 Gbps upstream too little bandwidth

6. NG-PON2 Technology Key attributes of technologies coming after 10G PON
40 Gbps speeds and higher
Up to 60 km of reach (GPON today can do 40 km, with limited splits)
Goal of a wavelength per home
Candidate technologies
40 GB/s TDMA and stacked 10 Gbps PONs- Too brunt force
OCDMA PON
WDM PONs- Commercially available, cost improvements needed
OFDM PON
Coherent PON- Brilliant proposal, capturing imaginations
Proposed by Nokia Siemens at FSAN meeting 11/2009
Key challenges to achieving commercial viability by 2015
No standard and many competing technologies and interests
Key challenges in cost and performance of components
